DL3889.The coordinates were established by GPS observations
DL3889.and adjusted by the National Geodetic Survey in January 2023.
DL3889
DL3889.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3889.been affixed to the stable North American Tectonic Plate.
DL3889
DL3889.The coordinates are valid at the epoch date displayed above
DL3889.which is a decimal equivalence of Year/Month/Day.
DL3889
DL3889.Due to the release of the International GNSS Service (IGS) 2014
DL3889.realization of the International Terrestrial Reference Frame of 2014
DL3889.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3889.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3889.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3889.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3889.currently published epoch of 2010.00.
DL3889
DL3889.Additional information on MYCS2 is available at
DL3889.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL3889.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3889.GEOID18 height accuracy estimate available here.

DL3889.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3889
DL3889.The ellipsoidal height was determined by GPS observations
DL3889.and is referenced to NAD 83.
